In July last I noticed that the leaves of the burdocks on the Heights of Levis were riddled as if from a discharge of small shot. On examination, I found that the damage to the leaves was caused by numerous larvæ of a species of Cassida. The creatures were there in strength, each supporting, by means of the forked prolongation of its anal segment, its “stercoraceous parasol.” Towards the end of the month the grim-looking pupæ were to seen, bristling round their edges with white branched spines, and attached to the leaves by a natural cement. In the present month (August) the beetles have appeared. They are about eight millimetres in length and five millimetres in breadth.

The genus Eremopedes was established by Scudder in 1894, CAN. ENT., XXVI., p. 178,181. It was founded on a femal specimen in the National Museum, but the species was not described till 1900. Previous to that date Mr. Cockerell described a species from New Mexico, together with a colour variety of the same, and I can now add a third species to the genus. In connection with its description it may be well to give a short account of the genus, which may be characterized as follows:

Insects of medium size. Head with the fastigium moderately prominent. Thorax with the prosternum unarmed.* Pronotum smooth, moderately rounded, nearly as much arched posteriorly as anteriorly, and without carinæ. Legs moderately spinose, hind pair long, the femora extending far beyond the tip of the abdomen, usually as much as half their length. Fore tibiæ spinded above on the outer margin only, the spines three in number. Ovipositor moderately curved upwards.

On April 27th, while collecting with my young son, Robert, the boy distinguished himself by capturing several ,♂ ♂ of Anæa andria, at a point east of Richmond, Ind., not far frorn the Indiana-Ohio State line. The authorities give the habitat of andria as “Western States, from Illinois to Texas; Nebraska.” No ♀ ♀ were seen nor were any specimens seen in the fall. I presume that south-western Ohio can be considered its most eastern habitat. No apparent difference exists between the specimens referred to and material from Texas and other western points.

Some lime ago, when about to publish a synopsis of the genus Scolops, the writer discovered that Dr. Uhler had the same genus in hand and his MSS. read for the press. As the result of the correspordence,the writer dropped his work for the time, and Dr. Uhler promised to send his types as soon as his paper was published. (Proc. Md. Acad. Sc., p. 401, 1900.) With his usual thoughtfulness, the Doctor sent on the types,and with the aid of these and a fine series of eastern forms received from Mr. Otto Heidemann the author has been able to definitely place all the described species and recognize a number of nerv ones.

The genus is found in its greatest abundance the border line of plain and mountain region, and so many rew forms have been found here in the past few years that there are no doubt many more to be found on further search.

In the following pages I have included descriptions of a few new genera and species of mites that have been in my possession for some time. Several of the genera are for the first time recorded in America. A note is added on two species of Trichotorsus. Of the two new genera, the Liroaspis is a very remarkable form, and funds its nearest allies in certain tropical species.

Trombidum granulatum, n. sp.– Bright blood red, the legs are clothed with scale-like hairs, those on the basal joints are white, elsewhere they are red, except on the apical joint of leg I., which is mostly white; the palpi and mouth-parts are mostly white, but reddish toward the trip. The body is covered above with rounded elevated granules, subequal in size and height; on the under side they are more scarce and there are some short red hairs. The body is hardly twice as long as broad, broadest at humeri, slightly constricted over base of the third legs, and broadly rounded behind; the dorsal outline at juncture of head and abdomen shows very little depression; on the cephalic part there is a median grove, and each side are two sessile eyes.

Phenacoccus cevalliæ, n. sp.

♀. Oval, 4 to 5 mm. long, pale olive green, but covered with white secretion, with lateral tassels and thick caudal tassels; placed in alcohol, they stain the liquid pale green; alcoholic specimens appear strongly segmented, with two longitudinal blackish bands, best marked in rather immature specimens. Eyes prominent; skin with many small circular glands; the lateral patches consist of about twelve glands each, but are without spines; a few rather large bristles scattered about the body; legs and antennæ reddish-yellow; denticle on inner side of claw rudimentary, just visible; antennæ 9-jointed, the club 2-jointed. Measurments of antennæ and legs in μ: Anterior legs, femur and trochanter 470, tibia 330, tarsus 130; hind legs, femur and trochanter 540, tibia 440, tarsus 135.

Carneades fusimacula, n. sp.

Resembles redimicula in most points, but with the colours of divergens. The collar has the broad median black shade fo redimicula; but the primaries do not have the pale costa. Sub-costal and median veins gray. Ordinary spots outlined in gray, the orbicular oblong, oblique, open inferiorly and fused with the reniform, the outline being continuous. The spots are gray powdered and are preceded by black shadings in the cell. A blackish basal streak, to which is joined a long claviform extending half way across the median space: this is blackmargined but concolorous. S.t. line not marked, apex grayish, terminal space else nearly concolorous. In other characters much like divergens, with which, also, it agrees in size.

The specimens on which this description is based are in the collections of the University of Nebraska and of the author. I owe especial acknowledgments to Mr. J. C. Crawfrod, Jr., for specimens and field observations, andto professor Bruner for directing my work.A sixteen-power glass was used in determining characters.

Myodites solidaginis, n. sp. – Female: Length, 7.9 mm. Head depressed, finely and evenly punctate, clad with dense yellowish-white, perpendicular pubescence; antennæ pectinate, ten-jointed, pubescent, very finely punctate, third joint with base of tooth yellowish; vertex between antennæ elevated; mandibles with the exterior side finely punctate, densely pubescent, grooved, in front and on interior sides shining glabrous. Thorax densely punctate, with median groove, but becoming mesially carinate behind the centre, clad with dense, upright, yellowish-white pubescence.

In 1834 Dejean proposed the name Euchætes for a genus of Coleoptera, and it had thus been preoccupied for seven years when Harris used it in 1841 for the moth named by Drury, Bombyx Egle.

In 1858 it was used for a third time by Sclater for a genus of birds, and in 1876 Leconte described another genus of Coleoptera under this same much-used name.

As it is a well-known rule of nomenclature that a generic name can be used only once in the animal kingdom, all subsequent use of the term for other genera is erroneous and must cease.

It therefore becomes necessary to give other names, and I propose the name EUCHÆTIAS, from a kindred Greek word, for the genus erected by Harris. It is not necessary for me to define the genus, as it is well known, and this is merely a necessary change of name, the type, of course, being Egle, Drury.

My friends have not always forgotten me, but have occasionally sent me live Saturnian chrysalids, spun up no doubt with the intention of the insect to emerge in America. Instead, the poor deluded creatures appeared as months in my German room, allowing me to deceive myself for the moment that in my German room, allowing me to deceive myself for the moment that I was at home. Cynthia, promethea, cecropia, polyphemus, io and even imperialis, came out as in America. The only difficulty I had was with my few cocoons of luna, the moths in some cases failing to expand their wings. But, if my memory does not fail, this accident happens also more especially with luna in the breeding cage at home. Amont the examples which emerged here is one small male, expanding 78 mil., which is the most curious example of the species I remember to have seen. The wings are almos prefectly expanded, a little unevenness of the costa of the right primary, which is somewhat concave, and a slight crumpling of the costal region of both secondaries, are traces of retarded development; the “tails” are fully out.

Phenacoccus acericola, n. sp.

Since 1880, when the above-named species was founded and described as the European Pseudococcus aceris, Geoff. (Phenacoccus), by Miss Emily A. Smith, it has untill recently been supposed to have been that species.

The latter part of 1890, Prof. Cockerell wrote me that he believed our species was distinct from that of Europe, and suggested that I should describe it as new if upon further investigation no reason appeared to the contrary. At the meeting of the Association of Economic Entomologists of 1891, at Denver, Colorado, he speaks of it as being without a name.

In September, 1899, I published an account of a new cherry pest, which I called the cherry fruit-fly (Bulletin 172, Cornell Experiment Station). As stated on pp.31 and 32 of this bulletin, the identity of the adult insect insect not then been established, although the evidence strongly indicated that it was the fly known as Rhagoletis cingulata, Loew. I kept my breeding cages containing the hibernating puparia of the insect in the warm greenhouse or insectary all winter, and on March 9th, 1900, the first cherry fruit-fly emerged. It did not disappoint my expectxtions, for it demonstrated beyond further doubt that this new cherry-fruit pest is Rhagoletis cingulata, Loew. By May 31st nine more fo the files had emerged, and then cherries near the insectary were nearly half grown. The flies continued to emerge until July 11th in my cages, and on June 30th I received word from Geneva that they were abundant about the trees where the fruit was ripening. This correspondent caught quite a number of the files with sticky fly-paper hung on a shingle in a tree; he said they seemed to be attracted to any bright-coloured thing like a new straw that.

Writing of this species in his magnificent work on the Butterflies of New England, Dr. Scudder said:

“ This butterfly is double brooded throughout the whole of its range, the first generation making its advent during the last week in May, the females emerging the first week in June, when the males are common. *** The second brood varies considerably in the time of its apparition. Mr. Saunders reports that the first butterflies appeared one year in London, August 2nd; while Mr. Lintner took the first at Albany on July 15th another year found them beginning to fly by the 7th, and one year even found them ‘very abundant’ on the 9th.***

Peridroma canities n. sp. – Form and markings of the Texan P. annexa, but of a different, dusty gray, colour and a little shorter winged. Primaries dusty gray, with a slight dusky shading along costa, against which the pale dots, marking inception of transverse lines, are relieved. T.p. line tolerably distinct, indentate interspaceally, with included pale shade. Veins marked with fuscous. T. a. line double, with a strong outward inflection above internal margin. Claviform blunt, filled in with fuscous. Orbicular with central dot. Reniform moderate,filled in with fuscous. Cell slightly darker shaded. Marking inconspicuous, concolorous. Hind wings (♀) white.

In the preparation of my Catalogue of the Coccidæ I was not able to find where Illiger had proposed or described the genus Lecanium, although Burmeister in his handbook of Entomology, Vol. II., p. 69 (1835), used this genus, giving Illiger as the authority. Burmeister described the genus and placed under it hesperidum, Linn., and several other species. My husband, Prof. C. H. Fernald, wrote to Mr. Theodore Pergande, inquiring if he could give me any information whether Illiger had really published this genus, and if so where it could be found.

In Supplement No. 1 to his work “Lepidoptera, Rhopaloceres and Heteroceres, Indigenons and Exotic,” dated Sept. 15th, 1898, Dr.Herman Strecker described a species under the above name as follows:

“At first glance might be taken for a small Nitela, but it is a darkr, warmer colour, more towards a rich chestnut. The t.p. is not so conspicuous, and is much more upright, and its course is rather from the costa outwardly oblique than inwardly oblique. One example has the space from the base to t.p. chestnut brown, exteriorly the t.p. is accompanied by a broad, paler ashen shade, beyond which the brown again prevails. In another the whole wing is brown, the t.p. only being discernible on the closest inspection. Beyond what I have mentioned, the differences between this and Nitela, excepting size, are not very marked. Expands one inch. Types, two examples from Chicago, Illinois.”

Eulecanium fraxini, n. sp.–Adult ♀ scale 6 mm. long, 5 broad,2 high; some individuals are practically circular in outline and variable in size. In July the scales are well covered with a grayish powdery secretion; this being removed they are reddish brown, considerably wrinkled and pitted, surface shiny, texture thick.

Boiled in potash the derm becomes very clear and transparent, showing some large gland-pits 24 μ in diameter. Mouth-parts, legs and anal plates tinged with yellow.

In his “Insect Book,” Dr. L. O. Howard states that the egg of Ranatra has not as yet been described from the United States. It is hoped that the following note may be of itterest to someone :

On June 24, 1900, the writer was so fortunate as to find a large number of these eggs at Pine Lake, near Lansing, Mich. As the eggs were not recognized at first, they were allowed to hatch, and the nymphs allowed to become about half-grown.

♀. –Length about 12 mm.; black; head and thorax with pale ochraceous or whitish hair, very short and thin on thoracic dorsum ; head ordinary, facial quadrangle square; vertex behind the ocelli finely roughened and punctnred; front below the ocelli punctured as well as grooved; facial foveæ broad, pale, closely adjacent to eyes; antennæ dark; clypeus thinly hirsute, shining, strongry but not densely punctured, no median smooth line; process of labrum truncate; maxillary palpi short; mesothorax shining, strongly but not densely punctured, metathorax very coarsely roughened, enclosure irregularly subreticurately ridged, but without a transverse bounding ridge; tegulæ dark, with a ferruginous spot; wings dusky with a yellow tint, nervures and stigma ferruginous, second submarginal cell broad; legs wholly dark; hind tibial spur of hind legs much curved; hair on inner side of basal joint of hind tarsi fulvous; abdomen shining, stronglyand closely punctured, finely pubescent at sides, but without dorsal hair-bands; fimbria fulvous.

Phenacoccus cevalliæ, n. sp.

♀. Oval, 4 to 5 mm. long, pale olive green, but covered with white secretion, with lateral tassels and thick caudal tassels; placed in alcohol, they stain the liquid pale green; alcoholic specimens appear strongly segmented, with two longitudinal blackish bands, best marked in rather immature specimens. Eyes prominent; skin with many small circular glands; the lateral patches consist of about twelve glands each, but are without spines; a few rather large bristles scattered about the body; legs and antennæ reddish-yellow; denticle on inner side of claw rudimentary, just visible; antennæ 9-jointed, the club 2-jointed. Measurments of antennæ and legs in μ: Anterior legs, femur and trochanter 470, tibia 330, tarsus 130; hind legs, femur and trochanter 540, tibia 440, tarsus 135.
